The Sanctuary House pub

You're on Tothill Street, practically in the shadow of Westminster Abbey, and this place feels like a proper local rather than a tourist trap—which is impressive given the postcode. The Sanctuary House is a Victorian building that's managed to keep its soul intact: dark wood, real ales on tap, and the kind of bar setup where you actually want to linger over a pint. Upstairs there's a dining room that serves proper British food without being fussy about it. It's the sort of place Westminster types and locals both claim ownership of, which tells you something's working right.
